Hey, 70's-90's Kids: You remember Spirograph, don't you?

Have you played with spirograph before? What are your favorite patterns to create? They used to be math toys for drawing, but now they're so much more. 

Spirographs were invented in the late nineteenth century by mathematician and electrical engineer Bruno Abakanowicz, but didn't become a popular toy until the 1960s. They allow you to create a wide range of kaleidoscopic designs by putting your pen into one of many holes in a set of interlocking gears, then using your pen to push the gears around an outer ring. Do you have a more tactile learner? If you are looking for a paper and pencil set for your kids the original Spirograph Set is really awesome. If you have a hands-on learner, one of those sets would provide hours of fun, crafting, and learning.

Do you Know how to use Spirograph?Really?

What is a Spirograph?

A Spirograph is a curve formed by rolling a circle inside or outside of another circle. The pen is placed at any point on the rolling circle. If the radius of fixed circle is R, the radius of moving circle is r, and the offset of the pen point in the moving circle is O, then the equations of the resulting curve is defined by:

x = (R+r)*cos(t) - O*cos(((R+r)/r)*t) y = (R+r)*sin(t) - O*sin(((R+r)/r)*t) (moving circle outside the fixed circle)

x = (R-r)*cos(t) + O*cos(((R-r)/r)*t) y = (R-r)*sin(t) - O*sin(((R-r)/r)*t) (moving circle inside the fixed circle)

How to use it?

Here is how you can use the controls in this Spirograph applet:

· The first three scroll bars in the control panel let you change R, r and O respectively.

You can use the next three scroll bars to change the color of the drawing. These scroll bars change the red, green and blue values of the color (in the range 0-255) respectively.

· The last scroll bar lets you choose the number of iterations for the Spirograph. Move it to beginning and then slowly increase it to see how many iterations it takes to complete the spirograph.

· You can use the Random button to select random values for the radii and color.

Wireless Charging: Chargers You’ll Actually Want Everywhere

Our range of wireless chargers blend in beautifully with your home, and can be placed where you need them the most. All without having to c...

Advantages of Wireless Charging

Wireless charging is convenient when electrical contacts are not acceptable and the battery is embedded in the product or when the product cannot be reached. Wireless charging is commonly used in medical devices and food products where electrical shock or bacteria levels must be kept to a minimum and no electrical contacts are allowed.

Wiring charging can also reduce the amount of cables and power adapters you need to have custom manufactured for your device or application.

Wireless charging can be sized to deliver 5W or 10W of energy to the battery. It can be a good solution to charge your battery. It can also charge you battery at a fast rate depending on the size of the battery pack.

In most applications the distance between the two coils is typically 5mm. It is possible to extend that range to at least 35mm.

Transcript of wireless charging steps

Mains voltage is converted into high frequency alternating current (AC).

The alternating current (AC) is sent to the transmitter coil by the transmitter circuit.  The alternating current then induces a time varying magnetic field in the transmitter coil.

Alternating current flowing within the transmitter coil induces a magnetic field which extends to the receiver coil (when within a specified distance).

The magnetic field generates current within the receiver coil of the device.  The process whereby energy is transmitted between the transmitter and receiver coil is also referred to as magnetic or resonant coupling and is achieved by both coils resonating at the same frequency.

Current flowing within the receiver coil is converted into direct current (DC) by the receiver circuit, which can then be used to charge the battery.

5 Sexiest Horror Movies of All Time

VR horror films you can watch on your phone right now. Just like every other genre, horror has its tropes, commonly recurring themes or ide...

SLEEPAWAY CAMP (1983)

Shy Angela goes to live with her cousin and eccentric aunt after a boating accident kills her father and brother. But it’s when she attends Camp Arawak and the people who tease her start turning up dead that the film really gets interesting. Sleepaway Camp is a basic 80s slasher flick set at a summer camp – or so it seems. The film promises the kind of explicit sex that other movies of this type deliver, which probably packed the theatre with more than a few fourteen-year-old boys, but it ends up turning the genre on its head somewhat by showing more guys than girls in short shorts and crop tops.

DON’T LOOK NOW (1973)

No sexy horror movie list would be complete without this disquieting thriller starring Donald Sutherland and Julie Christie. The two play a married couple who, after the death of their daughter, take a trip to Venice and encounter a clairvoyant who says she has a message for them from the beyond.

Yizhan I6S mini drone with camera HD 2MP

A new way to capture the moment and the happiness around us.

A few things worth pointing out:

The i6s has an integrated camera, and it’s a 2 megapixel one at that! Given the price point and overall size of the aircraft this is pretty respectable. I’ll discuss the actual performance of the camera, along with sample footage, in the flight test portion of the review.

The battery uses a single cell 3.7 volt 450 mAh configuration, which is – strangely, considering the sizeable capacity – built-in. Also unfortunately, as a replaceable battery would – all other things being equal – have been preferable.

The LED lights are four in number (excluding the camera indicator and the purely aesthetical glowing “eyes” of the aircraft) and very bright. There is also color coding to help distinguish direction when flying. Just exemplary!

What kind of drone are you looking for?

These are the drones that most people are familiar with. Camera drones are usually ready-to-fly quadcopters that have stabilized cameras for shooting video and stills. The more popular reasons include exploring the world from new perspectives, experiencing what it’s like to fly, and capturing memories in a completely new way is a perfectly good reason for wanting a camera drone.

It's also one of the most gentle fliers that I've ever seen. Here is my new drone JYU Hornets S. * 120km/h high speed overflew the FERRARI racing supercar. * Dual GPS auto positioning system, the accurate positioning location, perfect       advanced follower. * Intelligent battery could extend fly time for about 20 minutes, removable battery   are easy for change. * Two antennas on the top of the transmitter to ensure a stable radio coverage. * Hovering point,Center surroundings, Hot follow performance is a great friend of   photos and videos capturing.

Why are drone and quadcopter flight times so short?

The best batteries anybody knows how to make (lithium) just don't store that much energy. If you put a bigger battery in the drone, at some point it becomes too heavy to fly.

Batteries are expensive. Store bought quadcopters are small and utilize small, inefficient propellers. This culminates into a short flight time craft. The batteries charge slowly because of cheap batteries and low wattage output chargers. If you want 15+ minute flights, build your own quadcopter.

Try tips to extend the battery life of your quadcopter

Do you have a habit of recharging your battery days before you plan on using your new shiny toy? If so, you may be inadvertently shortening the life of your battery. Ideally, you want to charge your battery just a few hours before you plan on using your quadcopter. A rechargeable battery will lose a percentage of its charge each day that it’s left off of the charger.

Flying in the right conditions is also important. If you’re flying your device outdoors, you want to avoid flying during windy or rainy conditions. Wind will make it more difficult for your copter to turn, hover and remain stable, which will drain more power from the battery than usual. Rain can have the same effect.

Most quadcopters come equipped with mid-range batteries that really don’t offer you the longest flight time possible. If you really want longer flight times, you’ll need to upgrade to a battery with a higher mAh. Check your machine’s specifications for the maximum mAh your model can handle.
